Concept: personal standard of living is derived (largely) from the number of energy slaves you have working for you.
Likewise, increasing or decreasing activity can be tracked by energy (slave) consumption in each sector.
The following series are produced monthly by EIA that totals the energy consumption in the US in 4 sectors (Industry, Transport, Commercial, Residential) from all energy sources. They are a very seasonal noisy series, so we use a 12-point moving average to smooth things out. We then divide this by population to arrive at - energy slaves per person per year for each sector in BTU. The MA makes it lag a bit, but the series are so noisy you would likely not see anything interesting if you didn't have some sort of adjustment.
Over a longer time period an argument might be made for decreasing energy use based on increased efficiency. Over shorter timeframes - not so much. And if you look at all the sectors, things are all still trending down except residential.
